I have my cluster setup with 32 GB per node with 5 nodes in ES 1.5 cluster. But now I read in the Elasticsearch documentation that heap memory is recommended to be 30.5 GB or less so that ES would use 32 bit addressing. So, I bounced one node at time with 30 GB heap memory. So does this change the addressing from 64 bit to 32 bit? Or it would work only with complete cluster restart?
Request your clarification.
